Description

DISPOSITIF DE MISE SOUS VIDE D'UN RECIPIENT. DEVICE FOR VACUUMING A CONTAINER.
La présente invention a pour objet un dispositif amovible de mise sous vide d'un récipient ou d'une cuve de travail, destiné en particulier, mais non exclusivement, à être monté sur un appareil de traitement des aliments.The present invention relates to a removable device for evacuating a container or a working tank, intended in particular, but not exclusively, to be mounted on a food processing apparatus.
Des appareils de traitement des aliments permettant de couper, de battre ou de mélanger des matières alimentaires diverses contenues dans une cuve sont bien connus. Différents outils peuvent être montés sur un arbre passant à travers le fond de la cuve, ledit arbre étant entraîné par un moteur se trouvant dans un carter disposé généralement au dessous de la cuve.Food processing devices for cutting, beating or mixing various food materials contained in a tank are well known. Different tools can be mounted on a shaft passing through the bottom of the tank, said shaft being driven by a motor located in a casing generally arranged below the tank.
Toutefois certains aliments tel que, par exemple, le foie gras doivent être travaillés à l'abri de l'air pour éviter toute oxydation.However, certain foods such as, for example, foie gras must be worked in the absence of air to avoid any oxidation.
Pour traiter de tels aliments, il est déjà connu de réaliser des cuves étanches à l'intérieur desquel pénètrent des canalisations reliées à une pompe à vide. Mais un tel appareil est habituellement lourd, encombrant et coûteux.To treat such foods, it is already known to make sealed tanks inside which penetrate pipes connected to a vacuum pump. But such a device is usually heavy, bulky and expensive.
La présente invention a pour objet un dispositif amovible permettant la mise sous vide d'un récipient étanche à sa partie inférieure. L'étanchéité à la partie inférieure est réalisée par des moyens connus qui ne seront pas décrits.The present invention relates to a removable device allowing the evacuation of a sealed container at its lower part. Sealing at the bottom is achieved by known means which will not be described.
Selon la présente invention, le dispositif de mise sous vide d'une cuve ou analogue est caractérisé en ce qu'il comprend un corps creux dont une des extrémités peut être mise en relation avec l'intérieur de la cuve et dont la seconde extrémité comporte une vanne, la dite vanne étant reliée à un conduit traversant l'ensemble du dispositif et pénétrant à travers le couvercle à l'intérieur de la cuve. Selon une autre caractéristique de l'invention, le corps creux comprend au moins un piquage connecté par une canalisation avec une pompe à vide, un second piquage servant à monter un manomètre de contrôle.According to the present invention, the device for evacuating a tank or the like is characterized in that it comprises a hollow body one end of which can be brought into contact with the interior of the tank and the second end of which comprises a valve, said valve being connected to a conduit passing through the entire device and penetrating through the cover inside the tank. According to another characteristic of the invention, the hollow body comprises at least one connection connected by a pipe with a vacuum pump, a second connection used to mount a control pressure gauge.
Grâce au tube intérieur, il est possible d'introduire en cours de préparation des ingrédients fluides tels que des poudres ou du liquide sans détruire le vide régnant à l'intérieur de la cuve.Thanks to the inner tube, it is possible to introduce, during preparation, fluid ingredients such as powders or liquid without destroying the vacuum prevailing inside the tank.
D'autres caractéristiques avantages de l'invention apparaîtront au cours de la description qui va suivre d'un mode particulier de réalisation donné uniquement à titre d'exemple non limitatif en regard de la figure unique qui représente un dispositif selon l'invention en coupe verticale.Other advantageous characteristics of the invention will appear during the description which follows of a particular embodiment given solely by way of nonlimiting example with regard to the single figure which represents a device according to the invention in section. vertical.
Sur la figure unique on voit que le dispositif comprend une canalisation 1 qui est reliée à une source de vide (non représentée) telle qu'une pompe à palette ou analogue. Le dispositif désigné en général par la référence 10 peut être isolé de la source de vide par une vanne 2. La vanne 2 correspond avec l'intérieur du dispositif par un orifice radial 11. Le dispositif proprement dit comprend un corps creux 5 fermé par un couvercle 4. A l'opposé du conduit d'aspiration 1 est disposé un manomètre 6 de contrôle de la pression à l'intérieur de la cuve (non représentée). Le manomètre est branché sur le corps 5 par un piquage 12. Le corps 5 prend appui sur le couvercle 8 de la cuve, par l'intermédiaire d'un élément ou couvercle auxiliaire 7. Le couvercle 8 présente une couronne munie de moyens (non représentés) de fixation sur la cuve et des nervures 18 supportant un manchon central 19.In the single figure we see that the device comprises a pipe 1 which is connected to a vacuum source (not shown) such as a vane pump or the like. The device generally designated by the reference 10 can be isolated from the vacuum source by a valve 2. The valve 2 corresponds to the interior of the device by a radial orifice 11. The device itself comprises a hollow body 5 closed by a cover 4. Opposite the suction duct 1 is disposed a pressure gauge 6 for controlling the pressure inside the tank (not shown). The pressure gauge is connected to the body 5 by a nozzle 12. The body 5 bears on the cover 8 of the tank, by means of an auxiliary element or cover 7. The cover 8 has a crown provided with means (not shown) for attachment to the tank and ribs 18 supporting a central sleeve 19.
A l'intérieur du manchon central 19 est insérée une jupe 20 solidaire du corps creux 5. Le couvercle auxiliaire 7 présente une trémie centrale en entonnoir 13 dans laquelle vient reposer la. partie inférieure 21 du corps 5 conformée en tronc de cône. L'isolation vis à vis de l'extérieur est assurée par un joint 14 et par une joint 22.Inside the central sleeve 19 is inserted a skirt 20 integral with the hollow body 5. The auxiliary cover 7 has a central funnel hopper 13 into which comes rest it. lower part 21 of body 5 shaped as a truncated cone. Insulation from the outside is provided by a seal 14 and by a seal 22.
A la partie supérieure du corps 5 se trouve une vanne 3 pouvant être fermée à l'aide d'une manette 15. Au dessus de la vanne 3 est prévu un embout 16 permettant le raccordement à un réservoir d'eau ou de liquide et, par exemple, à un réservoir d'huile. A l'intérieur du corps 5 est prévu un filtre 10 laissant passer l'air, mais retenant les particules liquides ou solides afin que celles-ci ne puissent pénétrer dans la pompe à vide. La vanne 3 s'encastre à son extrémité inférieure dans un tube 17 qui traverse le couvercle auxiliaire 7 et le couvercle 8 et est maintenu par une pièce 9 de manière à ce qu'il y ait un contact direct entre la canalisation 16 et l'intérieur de la cuve. Bien entendu, le couvercle auxiliaire 7 est monté sur le haut de la cuve de travail par l'intermédiaire du couvercle 8 et d'un joint (non référencé) et de façon générale des joints d'étanchéité sont prévus, avec emplacements désirés notamment entre le couvercle 4 et le corps 5. La pièce 9 est vissée à la partie inférieure de la tige 17 et prend appui sur la surface inférieure des nervures 18. Outre son action de fixation mécanique, la pièce en cloche 9 assure un rôle de déflecteur pour éviter que les produits se trouvent dans la cuve ne montent dans le corps 5. En effet, dans un appareil de ce type, la matière est violemment agitée et des projections se produisent sur toutes les parois de la cuve. C'est pour cette raison que le diamètre de la cloche 9 est supérieur aux dimensions d'un écrou servant à assurer la fixation.At the upper part of the body 5 there is a valve 3 which can be closed using a lever 15. Above the valve 3 is provided a nozzle 16 allowing connection to a tank of water or liquid and, for example, to an oil tank. Inside the body 5 is provided a filter 10 allowing the air to pass, but retaining the liquid or solid particles so that these cannot penetrate into the vacuum pump. The valve 3 is fitted at its lower end into a tube 17 which passes through the auxiliary cover 7 and the cover 8 and is held by a piece 9 so that there is direct contact between the pipe 16 and the inside of the tank. Of course, the auxiliary cover 7 is mounted on the top of the work tank via the cover 8 and a seal (not referenced) and generally seals are provided, with desired locations in particular between the cover 4 and the body 5. The part 9 is screwed to the lower part of the rod 17 and bears on the lower surface of the ribs 18. In addition to its mechanical fixing action, the bell-shaped part 9 acts as a deflector for avoid that the products are in the tank do not go up in the body 5. Indeed, in an apparatus of this type, the matter is violently agitated and projections occur on all the walls of the tank. It is for this reason that the diameter of the bell 9 is greater than the dimensions of a nut used for fixing.
Le fonctionnement du dispositif est le suivant. La cuve étant une cuve de travail ordinaire, lorsque l'on souhaite opérer sous vide, on monte le corps 5 sur le couvercle auxiliaire 7 ce qui le maintient en position et la pièce 9 est vissée sur le couvercle 8. Après mise en marche de la pompe, la vanne 3 étant maintenue fermée la vanne 2 est ouverte par la manette 18 et le vide s'instaure progressivement à l'intérieur de la cuve.The operation of the device is as follows. The tank being an ordinary working tank, when it is desired to operate under vacuum, the body 5 is mounted on the auxiliary cover 7 which keeps it in position and the part 9 is screwed onto the cover 8. After switching on pump, valve 3 being kept closed, the valve 2 is opened by the lever 18 and the vacuum is gradually established inside the tank.
La pression atmosphérique n'étant plus équilibrée, le corps 5 est aspiré vers le bas ce qui écrase le joint 14 et assure une bonne étanchéité. En fonction des besoins de la préparation, le vide- peut être maintenu ou, par action sur la manette 18 de la vanne 2, la liaison avec la pompe peut être interrompue. Si, au cours de la préparation il est nécessaire d'introduire par exemple un liquide tel que de l'huile à l'intérieur de la cuve, on ouvre alors la vanne 3 par action sur la manette 15. La vanne 3 est reliée par l'embout 16 à un réservoir ( non représenté) et le liquide s'écoule par la vanne 3 et le tube 17 pour tomber directement dans la cuve dans l'axe de celle- ci où elle est reprise par le couteau tournant à la partie inférieure de la cuve. La vanne 3 est alors refermée et la préparation est poursuivie. L'introduction d'une quantité déterminée de liquide ne modifie pas sensiblement, la pression à l'intérieur de la cuve qui reste sous un vide primaire.The atmospheric pressure no longer being balanced, the body 5 is sucked down which crushes the seal 14 and ensures a good seal. Depending on the needs of the preparation, the vacuum can be maintained or, by action on the lever 18 of the valve 2, the connection with the pump can be interrupted. If, during the preparation it is necessary to introduce, for example, a liquid such as oil inside the tank, the valve 3 is then opened by action on the lever 15. The valve 3 is connected by the nozzle 16 has a reservoir (not shown) and the liquid flows through the valve 3 and the tube 17 to fall directly into the tank in the axis of the latter where it is taken up by the knife turning to the part bottom of the tank. The valve 3 is then closed and the preparation is continued. The introduction of a determined quantity of liquid does not significantly modify the pressure inside the tank which remains under a primary vacuum.
Après réalisation de la préparation, la cuve peut être ouverte après remise sous pression atmosphérique grâce à l'une des vannes 2 ou 3 et le couvercle 8 est retiré de la cuve.After completion of the preparation, the tank can be opened after return to atmospheric pressure using one of the valves 2 or 3 and the cover 8 is removed from the tank.
Ainsi la présente invention permet grâce à un montage très simple, d'utiliser une cuve normale en cuve travaillant sous vide. De plus, elle permet d'introduire, en cours d'opération des ingrédients divers, sans "casser" le vide. Thus the present invention allows, thanks to a very simple assembly, to use a normal tank in a tank working under vacuum. In addition, it allows the introduction, during operation of various ingredients, without "breaking" the vacuum.
